TC1303A/TC1303B/

TC1303C/TC1304

500 mA Synchronous Buck Regulator,

+ 300 mA LDO with Power-Good Output

Features

Description

• Dual-Output Regulator (500 mA Buck Regulator

and 300 mA Low-Dropout Regulator)

The

TC1303/TC1304

combines

500 mA

synchronous buck regulator and 300 mA Low-Dropout

Regulator (LDO) with a power-good monitor to provide

a highly integrated solution for devices that require

multiple supply voltages. The unique combination of an

integrated buck switching regulator and low-dropout

linear regulator provides the lowest system cost for

dual-output voltage applications that require one lower

processor core voltage and one higher bias voltage.

• Power-Good Output with 300 ms Delay

• Total Device Quiescent Current = 65 µA, Typical

• Independent Shutdown for Buck and LDO

Outputs (TC1303)

• Both Outputs Internally Compensated

• Synchronous Buck Regulator:

- Over 90% Typical Efficiency

The 500 mA synchronous buck regulator switches at a

fixed frequency of 2.0 MHz when the load is heavy,

providing a low noise, small-size solution. When the

load on the buck output is reduced to light levels, it

changes operation to a Pulse Frequency Modulation

(PFM) mode to minimize quiescent current draw from

the battery. No intervention is necessary for smooth

transition from one mode to another.

- 2.0 MHz Fixed-Frequency PWM

(Heavy Load)

- Low Output Noise

- Automatic PWM to PFM mode transition

- Adjustable (0.8V to 4.5V) and Standard

Fixed-Output Voltages (0.8V, 1.2V, 1.5V,

1.8V, 2.5V, 3.3V)

The LDO provides a 300 mA auxiliary output that

requires a single 1 µF ceramic output capacitor,

minimizing board area and cost. The typical dropout

voltage for the LDO output is 137 mV for a 200 mA

load.

• Low-Dropout Regulator:

- Low-Dropout Voltage = 137 mV Typical @

200 mA

- Standard Fixed-Output Voltages

(1.5V, 1.8V, 2.5V, 3.3V)

For the TC1303/TC1304, the power-good output is

based on the regulation of the buck regulator output, the

LDO output or the combination of both. The TC1304

features start-up and shutdown output sequencing.

• Power-Good Function:

- Monitors Buck Output Function (TC1303A)

- Monitors LDO Output Function (TC1303B)

- Monitors Both Buck and LDO Output

Functions (TC1303C and TC1304)

The TC1303/TC1304 is available in either the 10-pin

DFN or MSOP package.

- 300 ms Delay Used for Processor Reset

• Sequenced Startup and Shutdown (TC1304)

• Small 10-pin 3x3 DFN or MSOP Package Options

• Operating Junction Temperature Range:

- -40°C to +125°C

Additional protection features include: UVLO,

overtemperature and overcurrent protection on both

outputs.

For a complete listing of TC1303/TC1304 standard

parts, consult your Microchip representative.

• Undervoltage Lockout (UVLO)

• Output Short Circuit Protection

• Overtemperature Protection

Applications

• Cellular Phones

• Portable Computers

• USB-Powered Devices

• Handheld Medical Instruments

• Organizers and PDAs
